SymCom’s ISS-102ACI-MC dual-channel switch is designed that the intrinsically-safe inputs are compatible with normally open (N.O.) or normally closed (N.C.) switches, as well as resistive probes. Input logic can be either direct or inverted. Input debouncing is selectable to either 0.5 or 2 seconds. For pumping applications, differential/latching logic can be selected. Green LEDs illuminate on the ISS-102ACI-MC when the associated output relay is energized.
